Advantages of the invention:

1. The present invention combines two flexible soil cleaning methods: pneumatic force and brush to minimize damage to the grapevines. The high-speed and high-pressure wind will destroy the original state of the buried soil. After the soil is loosened, it will move with the air flow. The rotating brush can not only continue to destroy the original state of the buried soil, but also brush the soil particles that are loose and moved with the air flow to the rows. . The two flexible soil cleaning methods of air force and brush will not damage the grapevines, and the brush can brush the soil particles between the rows for burying in winter.

2. The lifting plate of the present invention combined with the expansion and contraction of the hydraulic cylinder can realize the lifting and lowering of the brush body. When the tractor turns at the edge of the field, it lifts the brush body and lowers it when it reaches the working position, thereby avoiding damage to the brush body.

3. The air outlet orientation adjustment device of the present invention is composed of an air outlet position adjustment rod and an air outlet adjustment device. It can realize the horizontal angle and position adjustment of the air outlet position and the fixed-point three-dimensional space rotation adjustment, which is conducive to different soil quality and operating conditions. Adjustment of the air outlet improves the versatility of the machine.

4. The brush body of the present invention is composed of multi-piece inlays. The lower brush blade is easy to wear. The multi-piece inlay combination eliminates the need to replace the entire brush blade when replacing it, thus saving operating costs.

5. The machine tool described in the present invention is connected to the tractor in a three-point traction type. The three-point traction can better control the driving path of the machine tool and enable the machine tool to better complete the work.

The general working process of the present invention is as follows: the present invention adopts a unilateral soil clearing method. The hydraulic system required for the hydraulic cylinder 25 uses the hydraulic system of the tractor. The three-point suspension of the tractor is connected with the three-point connection of the air-blown grapevine buried soil removal machine. 2. Connect the tractor's power output shaft to the front axle 9 with a universal joint. When clearing soil, the three-point connection behind the tractor pulls the air-blown grapevine buried soil remover between the grape rows. The brush end is close to the soil ridge to be cleared. Adjust the hydraulic handle of the tractor so that the hydraulic cylinder 25 is in an extended state. According to the height difference between the ground and the moldboard 33, adjust the moldboard support tube 34 so that the height difference between the moldboard 33 and the ground is at a suitable position. When the tractor is moving, the front axle 9 transmits the power from the tractor power output shaft to the gearbox 3. The output power of the gearbox 3 is transmitted to the rear axle 11 and the upper axle 13 respectively. The rear axle 11 drives the fan 27 to rotate through the fan pulley assembly. The high-speed rotating fan 27 generates high-speed and high-pressure wind, which is transmitted through the air pipe 30 to the air outlet 31 on the left side of the machine. At this time, by adjusting the air outlet position adjustment rod and the air outlet adjustment device 32, the high-speed and high-pressure wind is blown to the soil ridge where the brushes contact; the upper shaft 13 transmits the power to the brush shaft 26 through the brush pulley assembly, and then The brush shaft 26 transmits power to the brush body, and the rotation of the brush body will destroy the original state of the buried soil, and brush loose soil particles that move with the airflow to the rows. The buried soil that is brushed to the rows will gather near the brush and cannot be evenly spread between the rows. At this time, the scraper 33 will evenly scrape the unevenly distributed buried soil to the rows, making it easier to bury the soil in the next winter. Take soil. When turning at the edge of the field, the tractor operator first disconnects the power of the tractor's power output shaft and adjusts the tractor's hydraulic handle so that the hydraulic cylinder 25 is in a compressed state. At this time, the brush body will also be lifted to avoid collision damage between the brush body and other objects. When the machine tool is towed to the next working location, repeat the above actions.
